38 // In addition to the default jQuery Widget methods, the fileupload widget
39 // exposes the "add" and "send" methods, to add or directly send files using
40 // the fileupload API.
41 // By default, files added via file input selection, paste, drag & drop or
42 // "add" method are uploaded immediately, but it is possible to override
43 // the "add" callback option to queue file uploads.

54 // If undefined, it is set to the file input fields inside
55 // of the widget element on plugin initialization.
56 // Set to null to disable the change listener.
58 // By default, the file input field is replaced with a clone after
59 // each input field change event. This is required for iframe transport
60 // queues and allows change events to be fired for the same file
61 // selection, but can be disabled by setting the following option to false:
62 replaceFileInput: true,
63 // The parameter name for the file form data (the request argument name).
64 // If undefined or empty, the name property of the file input field is
65 // used, or "files[]" if the file input name property is also empty,
66 // can be a string or an array of strings:
68 // By default, each file of a selection is uploaded using an individual
69 // request for XHR type uploads. Set to false to upload file
70 // selections in one request each:
71 singleFileUploads: true,
72 // To limit the number of files uploaded with one XHR request,
73 // set the following option to an integer greater than 0:
74 limitMultiFileUploads: undefined,

76 // in a sequential order:
77 sequentialUploads: false,

79 // set the following option to an integer greater than 0:
80 limitConcurrentUploads: undefined,
81 // Set the following option to true to force iframe transport uploads:
82 forceIframeTransport: false,
83 // Set the following option to the location of a redirect url on the
84 // origin server, for cross-domain iframe transport uploads:
86 // The parameter name for the redirect url, sent as part of the form
87 // data and set to 'redirect' if this option is empty:

90 // to enable postMessage transport uploads:
91 postMessage: undefined,
92 // By default, XHR file uploads are sent as multipart/form-data.
93 // The iframe transport is always using multipart/form-data.
94 // Set to false to enable non-multipart XHR uploads:
96 // To upload large files in smaller chunks, set the following option
97 // to a preferred maximum chunk size. If set to 0, null or undefined,
98 // or the browser does not support the required Blob API, files will
99 // be uploaded as a whole.
100 maxChunkSize: undefined,
101 // When a non-multipart upload or a chunked multipart upload has been
102 // aborted, this option can be used to resume the upload by setting
103 // it to the size of the already uploaded bytes. This option is most
104 // useful when modifying the options object inside of the "add" or
105 // "send" callbacks, as the options are cloned for each file upload.
106 uploadedBytes: undefined,
107 // By default, failed (abort or error) file uploads are removed from the
108 // global progress calculation. Set the following option to false to
109 // prevent recalculating the global progress data:
110 recalculateProgress: true,
111 // Interval in milliseconds to calculate and trigger progress events:
112 progressInterval: 100,
113 // Interval in milliseconds to calculate progress bitrate:
114 bitrateInterval: 500,
116 // Additional form data to be sent along with the file uploads can be set
117 // using this option, which accepts an array of objects with name and
118 // value properties, a function returning such an array, a FormData
119 // object (for XHR file uploads), or a simple object.
120 // The form of the first fileInput is given as parameter to the function:
121 formData: function (form) {
122 return form.serializeArray();
125 // The add callback is invoked as soon as files are added to the fileupload
126 // widget (via file input selection, drag & drop, paste or add API call).
127 // If the singleFileUploads option is enabled, this callback will be
128 // called once for each file in the selection for XHR file uplaods, else
129 // once for each file selection.
130 // The upload starts when the submit method is invoked on the data parameter.
131 // The data object contains a files property holding the added files
132 // and allows to override plugin options as well as define ajax settings.
